SpamHound SMS Spam Filter

Tired of promotional and spam messages? SpamHound makes blocking texts simple with privacy-first filtering. Create unlimited blocking rules for SMS and MMS, manage Blacklists and Whitelists, and stop messages from short numbers or emails - without needing access to your message content. The extension works offline, so you stay protected even without internet.

Key features include unlimited filtering, flexible rule syntax (including regex and wildcard), automatic rules to block links, a dedicated Junk SMS tab, and a Whitelist to prevent accidental blocking. Backups let you sync rules across devices via linked social accounts, ensuring you stay protected wherever you go.
